BROODER.

Specification of Letters Patent.

Patented apr. a, 191s.

i Application filed October` 13, 19.17. Serial No. 196,536.

To all whom t may concern.'

Be it known that I,` Mrs. MARY MiLLER, a citizen of the United States, residing at Theresa, in the county of Dodge and State of W'isconsin, have invented new and useful Improvements in Brooders, of which the following is a specification. i

This invention is an improved brooder, the object of the invention being to provide a brooder of novel construction, which is cheap and simple, which is portable and may be readily and easily cleaned, and which avoids the use of a lamp or heating device of any kind in which fuel is consumed, so that all danger of setting fire to the brooder and to the building in which the same is used is entirely avoided; anotherl object being to provide an improved brooder in ,which the temperature can be readily maintained at the desired point and which affords thorough ventilation and keeps the chicks warm and comfortable and under such conditions as to greatly promote their growth and development. v

The invention consists in the construction,l combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is a perspective view of a brooder constructed and arranged in accordance with my invention.

Fig. 2 is a longitudinal sectional view of the same.

Fig. 3 is a transverse sectional view of the same.

Fig. 4 is a detailed plan of the heating tank.

My improved brooder comprises a bottom 1, a roof 2, end walls 3, a front wall l and a rear wall 5. The roof, walls and the bottom are made of suitable lumber, usually three-fourths of an inch thick, and lined on the outside with water proof paper or other suitable water proof material, indicated at 6, and covered with galvanized iron as at 7 and are also lined on the inside with a double thickness of water proof paper as at 8. Blocks 9 are secured under the corners of the brooder to raise the bottom thereof above the floor or ground and to permit air to circulate beneath the brooder to keep the same dry and promote the healthfulness of the chicks. An entrance opening at 10 is in the front wall of the brooder at a point near the center thereof and may be covered by means of a slide 11 which is preferably made of galvanized iron. The rear wall 5 of the brooder has an opening 12 of suitable size and a slide 13 'to' close said opening. On the ends of the brooder are handles 14 each of which comprises a bar 15,v the ends of which are secured on bracket blocks 16 so that the handle bars are spaced from the end Walls of the brooder as shown. Each end wall has a Ventilating opening 17 near the top and a slide 18 to cover or partly .cover said opening as may be desired.

The brooder is gabled and the top or roof comprises a front member 19 and a rear member 20. The rear member is rmlysecured. The front member is hinged, at the ridge, to the rear member as at 21 so that the front member can be raised or lowered, to open or close the brooder, as may be desired. In the ends of the front member are openings 22 which are provided with glass panes 23 to admit light. The ridge of the roof may be closed by a galvanized iron ridge cap 24.

The brooder is heated by heat radiated from a tank 25 which contains hotwater. The tank is of suitable capacity and proportion according to the size of the brooder and is preferably made of galvanizedk iron, is

of oblong rectangular form and is provided filled with boiling water, if desired. and to regulate the heating effect of thetank by opening or closing the valve, as will be understood. The tank has hollow ends OtoA enable the tank to be readily handled by grasping the same at the ends. The top,

vsides and ends of the tank are covered with non-conducting material 31 such as heavy perforated ridged or corrugated paper and the bottom of the tank is covered with paste-board or other suitable insulating material 32. An outer covering 33 of canvas is secured around the tank and is sewed with binding cord at the back and at the ends of the tank. I

The tank is arranged in the brooder, 1s movable therein and removable therefrom,

and when in place is supported on bars 33 which eXtend transversely across Athevbrooder and the ends of Which are supported on strips 34 which are secured on the opposing sides of the front and baok of the brooder and at a height of about nine inches above the floor or bottom so that the tank is supported at an appropriate height above the bottom of the brooder and substantially in the center thereof and heat radiated from the `tank extends to all portions of the brooder and the saine is heated at all points to a substantially even degree of temperature. opposite the opening 10 and When it is desired to empty the tank and to refill the same with hot Water vthe tank is moved at the back of the brooder so that its arm 2G is caused to project through the opening 12 l thus. exposing the filling and emptying nipples and enabling the tank to be emptied.

and refilled Without the necessity of reinoving the tank from the brooder and Without danger of spilling any Water in the brooder. When the tank is removed from the brooder the Abars 33 may be also removed so that the interior of the brooder is' entirely unobstructed and the saine may be readily and thoroughly cleaned. Preferably the bottom -v of the brooder is covered by a piece of removable fabric 85, such as roofing `fabric or the like, which may be readily taken out of the brooder and cleaned.l A piece of pastebo-ard 36, or other suitable material, may be placed over thetank and a blanket 37 or Copies of this patent may he obtained for five cents each, by addressing Washington, D. C.

rIhe arm 26 of the tank is arrangedv other suitable fabric may be placed over said paste-boardandlarranged with its ends hanging dovvn therefrom Within a feW inches of the bottom of the brooder, to concentrate heat in the center of the brooder under the tank and to allow chicks tol pass freely either to the more highly heated spaceor to the ends ofthe brooder as they may desire.

My brooder is extremely cheap and simple7 may be readily moved from place to place,l may be readily cleaned and kept supplied With hot water, is not liable to injure the chicks and is entirely free from danger of starting'a lire as the use of a lainp or other dangerous heating medium is entirely avoided. l

lVhile I have herein shown and described a preferred form of my invention, I would have it yunderstood that changes may be made in the form, proportion'and constructionvof the several p arts without departing from the spirit of my invention and-Withiny the scope of the appended claim.

Having thus described my invention, I

claim A brooder structure having an opening in one of its Walls and a heating tank in the structure and movable toward and from said Wall, said tank having lan arm adapted to project through said opening when said tank is arranged near ysaid Wall and being provided with filler and emptying means.y

In testimony whereof I aiiix my signature.
